iamcter iiesorihsri of Fig. 2) representsthe beam merging with the door,the parts shown in section 1n Fig. 3 being enlarged somewhat to betterbring out the relation of the several elements of our invention. Partsshown but not re erred to ere Well known in the artaud require nodescription in the present connection. As shown iu the drawings, the enchers or clasps are disposed across the ispjoint between the sheets a,and distributed to the required number along the joint. The sheets arethus effectively held against, displacement, and economyfin the use ofthe sheets results. In the ismsntling of tbe falsework, the sheets arereadily pulled away from the clasps, and the parts may be used again forthe nextjob.

Having described our invention, what we claim is: Y-

1. A concrete-Hoor decking comprising series of sheets of, thin materialwith adjacent edges overlapped, clasps having each a medial or bodyportion interposed between the sheets and across the lap-joints formedby the sheets, and outer spring arms engug img the outer feces of. therespect-ive sheets und clasping the same to the medial portion, andcorrugated sheets supporting the overlapped 'thin sheets, the bottomseries oit arms of the olas being adapted to rest in the depressionsormed by the corrugetions.

2. A concreteloor decking comprising .series of sheets of thin materielwith zuljiu cent edges overlapped, clasps having each a medial or bodyportion interposed betr-reen the sheets and across the lap-joints formedby the'sheets, and outer spring arms engegJ ing the outer 'faces of therespective sneeis,

and clasping the seme to the medial. portion, eind corrugated metalsheets supporting the overlapped thin sheets, the bottom ies of arms otthe clasps engaging the corrugated sheets.

3. A concrete-50er decking comprising series of sheets of thin materialwith adjacent edges overlapped, clasps Aformed of s single strip ofmetal and having each a media-l or body portion interposed bet-Ween thesheets and disposed across the lap-joints between the sheets, and outerspring arms extending in opposite directions from the opposite ends ofthe medial portion and terA minating a suitable distance beyond the endsof the medial portion whereby the sheets are guided into positionbetween the arms4 and medial portions7 and corrugetml sheets of metalfor the support of the thin sheets the bottoni series of arms ci theclasps rest4 i ing on the corrugated sheets.

in testimony whereof we :illix our siguetures, in presence of twoWitnesses.
